A sprawling and evocative trip through the landscape of American music of the last century, Harmony is a new group that continues Frisell’s career-long exploration of the breadth and scope of American music. Drawing on influences from folk, bluegrass and country as well as jazz, Harmony brings together collaborators from throughout Frisell’s notable career: vocalist Petra Haden, who has performed extensively in duos with the guitarist as well as on his movie-music tribute When You Wish Upon a Star; Roberts, whose association with Frisell spans three decades, dating back to the 1987 ECM release Lookout for Hope; and Bergman, a fellow member of the University of Washington Jazz Studies faculty and member of the Cuong Vu Group, which has recorded with Frisell.

Bill Frisell’s career as a guitarist and composer has spanned more than 35 years and many celebrated recordings. His catalog has been cited by Downbeat as “the best recorded output of the decade.” Over the years, Frisell has contributed to the work of such collaborators as Paul Motian, John Zorn, Elvis Costello, Ginger Baker, The Los Angeles Philharmonic and numerous others. This work has established him as one of the most sought-after guitar voices in contemporary music. The breadth of such performing and recording situations is a testament not only to his singular guitar conception, but his musical versatility as well.

In a restlessly eclectic, wholly unique musical career that spans two and a half decades, Petra Haden, daughter of legendary jazz bassist Charlie Haden, has established a singular reputation for creativity and versatility, and a unique niche that's allowed her to apply her multiple talents to a dazzlingly diverse array of music. As a singer, instrumentalist and composer, Haden has built an impressively varied and accomplished discography encompassing her work as part of the beloved alt-rock quartet That Dog, her collaborations with a broad array of acts, and a series of her own releases, which often showcase her unique talent for constructing complex, evocative a capella arrangements by inventively layering multiple tracks of her own voice.

Over his nearly four-decade career, Hank Roberts has forged a compelling original voice as a composer and a cellist, encompassing abstract improvisation, jazz influences, soulful folk melodies, intricate new-music compositions and vigorous rock songs. Roberts made his name in the legendary 1980s New York Downtown scene. Faced with a dearth of improvisational cellist mentors or peers, he carved his own path through that fertile ground alongside such frequent collaborators as Bill Frisell, Tim Berne, Marc Ribot and John Zorn, finding a second home at the famed Knitting Factory, leading and recording with his own groups, ‘Birds of Prey, ‘Black Pastels’, ‘Little Motor People’ and co-founding ‘Miniature’ with Tim Berne and Joey Baron, and the ‘Arcado String Trio’ with Mark Feldman and Mark Dresser. The list of names with whom Roberts has shared stages or recording studios with includes Gavin Friday (with the members of U2), Sting, Jeff Buckley, David Sanborn, Mamadou Diabate, Andy Summers, Gary Burton, Marty Ehrlich, Arto Lindsey, Gerry Hemingway, Don Byron, and Julius Hemphill. He is currently a member of Bill Frisell’s 858 Quartet and Big Sur Quintet, and appeared on the guitarist’s Grammy-winning 2004 release Unspeakable. He’s recorded 10 albums on the ‘Winter & Winter’ label, along with numerable self-released recordings. His solo performances are singularly compelling and unpredictable, wending from jagged dissonance to intoxicating pop songcraft.

An innovative bassist, composer and producer who is constantly putting forth spirited work, Luke Bergman has become an integral part of the Pacific Northwest music scene. His artistic and educational efforts as well as his dedication to creative music have served as a touchstone for a new generation of Seattle musicians.Bergman's music has garnered critical acclaim on a national and international level for his work with Heatwarmer, Speak, Thousands, and The Cuong Vu Group. He is dedicated to the development of the local music community and serves as co-creator, organizer and artistic director of The Racer Sessions, a weekly performance series which is devoted to the advancement of avant-garde music in Seattle. Bergman also serves as a board member, producer, recording engineer and co-founder of Table and Chairs Music, a not-for-profit, independent record label that documents and promotes creative music in Seattle.
